Large crystal grains in an igneous rock are an indication that crystals formed?

slowly from a magma with abundant time to grow. This can suggest an intrusive or plutonic igneous rock type, such as granite. Rapid cooling leads to small crystal grains, characteristic of extrusive or volcanic igneous rocks like basalt.


Does slow cooling of igneous rocks form large or small crystal grains?

Slow cooling of igneous rocks typically forms large crystal grains. This is because slow cooling allows more time for mineral grains to grow, resulting in larger crystals. Examples of rocks formed through slow cooling and having large crystal grains include granite and gabbro.


Igneous rock that forms deep inside the earth and has large mineral grains is called?

What does an igneous rock's crystal grain size indicate to the observer?

The size of the mineral crystals in an igneous rock is related to the rate of time spent in cooling from magma. Longer exposure to the crystallization temperature means larger crystals. Less time means smaller crystals, or in the case of obsidian, which cools extremely quickly, no crystallization.

Which rocks has two different size grains of the same mineral?

Pegmatite is a type of igneous rock that can have two different grain sizes of the same mineral present. This is due to the slow cooling process of the magma, allowing for the growth of large crystals (phenocrysts) within a finer-grained matrix.


What type of igneous rock has large mineral grains?

Intrusive igneous rocks since they have more time to cool, thus more time for the crystals o form and grow. So, examples of such igneous rocks will include:-Granite-Gabbro
